Abstract: An impact testing machine is configured. The impact testing machine includes: a testing machine body that applies a load having a prescribed speed to a test piece and conducts a test; a controller that controls the testing machine body; a video camera that photographs the test piece; and a pulse generator. The controller includes: a detection signal capturing unit that captures a detection signal of the load in a prescribed measurement sampling period; and a synchronizing signal output unit that outputs a sampling synchronizing signal that is synchronized with the measurement sampling period. The pulse generator includes: a photographing instruction signal generator that generates a photographing instruction signal by multiplying or dividing the sampling synchronizing signal, and outputs the photographing instruction signal to the video camera. The photographing instruction signal issues a photographing instruction to the video camera.

Abstract: Disclosed are an image pickup device and an imaging apparatus using the image pickup device. The image pickup device a photodiode for converting incident light to electric charge and generate a signal charge corresponding to an intensity of the incident light, a CCD cell for accumulatively storing respective signal charges generated from the photodiode, and transferring the signal charges to outside. In the image pickup device, a light-receptor board formed with the photodiode and a CCD-cell board formed with the CCD cell are arranged separately from each other and electrically connected to each other.
